Section 3 is a short introduction to the physics of neutron stars, with a focus on the equation of state and the neutron star mass–radius relations. In Section 4, we review existing neutron star constraints on dark neutrons [23,24,25,26,27], and discuss neutron decays into dark quarks ...
Neutron stars are highly dense remnants of massive stars that have collapsed, composed mainly of neutrons and other elementary particles. They are observable due to their strong magnetism, rapid rotation, and emission of radio radiation in a narrow cone. ...
Neutron stars consist of extremely dense nuclear matter. Their maximum size and mass are determined by their equation of state, which in turn depends on the interaction potentials between nucleons. Due to the high density, not only neutrons but also heavier strange baryons may play a role. ...
ABSTRACT. The maximum mass of neutron stars (MTOV) plays a crucial role in understanding their equation of state (EoS). Previous studies have used the meas
the pulse duration of the gamma-driven neutrons is much shorter52,53due to the relativistic feature of the electron beam generatingγ-rays. Nowadays, the high-yield laser-drivenγand neutron-beam production schemes are based on applications of high-intensity multi-petawatt-class laser systems, wher...
Neutron stars are presumably born after the supernova explosions of massive stars. They are believed to have an onion-like structure that schematically consists of a crust dominated by nuclei and a liquid nuclear matter in the core whose dominant component are neutrons, with some fractions of prot...
The advent of High Currenct Accelerator-driven Neutron Surces (HiCANS) will make access to neutrons easier than today’s sources. With HiCANS, large universities and research centres will be able to host their own neutron sources, gaining independence from large facilities using nuclear reactors ...
It should be stressed that the estimated tempera- ture within this simple approximation only accounts for contributions of the ideal gas of neutrons and protons (mass differences have been neglected). Especially at the low-density regions of the outer crust of the hybrid star (which is composed ...

Despite the notion, cool neutron stars accommodate, in the crust, various nuclei immersed in a degenerate electron-muon environment (maybe as “pasta” or “spaghetti” or crystalline medium). In the deeper interior, above the neutron drip density, neutrons and light clusters begin to dominate ...
